Enchantment/relic cleanup 3

[olanti-p]

Summary

SUMMARY: Infrastructure "Finish enchantment values code cleanup"

Purpose of change

Continuation of #400
Completes steps 1 and 2 of #1816

Describe the solution

1. Add strict json check for legacy enchant values' names
2. Check, implement, add tests and/or write docs for the following values:
   • STAMINA_CAP
   • STAMINA_REGEN
   • THIRST
   • FATIGUE
   • BONUS_DODGE
   • ITEM_ARMOR_*
   • ARMOR_*
   • ITEM_DAMAGE_BASH
   • ITEM_DAMAGE_CUT
   • ITEM_DAMAGE_STAB
3. Remove all other unimplemented enchantments from docs and from the enum. Some of these are tricky to implement cleanly and wouldn't have use at the moment, so I'd rather avoid spending time on these now. This way, all enchant vals are implemented and tested, which is good enough by itself.

Testing

Wrote some tests.

I didn't test how well does it handle legacy JSONs. Will it still understand them, just complain, or will it fail?

It fails to load when it encounters removed values, and turns out that kinda broke some mods. Pushed a hotfix (#2281)
